Ditto for wanting a better UX on this. I somewhat understand the technical reasons, but Evernote team is so awesome, I'm sure they can address this in an elegant way. Here is your user story: As a small team, we would like to share a notebook in a way that lets everybody on the team tag notes, so that the person who shared the notebook doesn't have to do all the tagging. One possible way to work this would be to add a permission level. Currently, it's read, modify. Maybe read, modify, and 'full', where 'full' would allow the user to tag and any other "special" tasks. Honestly, though, I tend to agree with the user who says "If I share a notebook, I generally trust the person not to pollute my tags.
